How inflammatory arthritis can affect the spine and sacroiliac joints, and why coordinated care matters.
Request My ConsultationUnderstanding ankylosing spondylitis
Ankylosing spondylitis, or AS, is an inflammatory form of arthritis that commonly affects the spine and sacroiliac joints. It is different from ordinary degenerative arthritis. Ongoing medical treatment and attention to movement are central to care.
Common symptoms
- Back or hip pain with stiffness, often more noticeable after rest.
- Reduced spinal flexibility or difficulty maintaining posture.
- Symptoms in other joints or outside the spine in some people.
What can cause it?
AS involves inflammation related to the immune system. Genetics can contribute, but no single risk factor establishes the diagnosis. Over time, inflammation may lead to structural changes and reduced movement in parts of the spine.
How it is evaluated
Evaluation considers the symptom pattern, family history, examination, and imaging of the spine or sacroiliac joints. Blood tests can contribute, but there is no single definitive test. Rheumatology assessment helps distinguish AS from mechanical back pain.
Treatment considerations
These are general educational options. A consultation helps determine what is appropriate for your diagnosis and health.
